New Mexico Community Property: Who Owns What When a Spouse Dies

New Mexico spouses each own half the community property. NMSA 45-2-807 gives the survivor their half, and intestacy sends the decedent's half to the spouse too.

By Settled Editorial

New Mexico is a community property state. Property either spouse acquires during the marriage belongs to both in equal, undivided halves, and death splits the halves cleanly. NMSA 45-2-807 states it in one sentence: "Upon the death of either spouse, one-half of the community property belongs to the surviving spouse, and the other half is subject to the testamentary disposition of the decedent."

That sentence, and the definitions behind it, decide what a New Mexico will can reach, why a widow already owns half the house before probate opens, why joint-tenancy titling changes the answer, and what basis an heir takes at sale. Every rule below was read at the official New Mexico Statutes Annotated on NMOneSource, the Compilation Commission's official source, on August 16, 2026. For the court process that handles the decedent's half, start with how New Mexico probate works.

New Mexico Sorts Property Into Two Kinds

NMSA 40-3-8, "Classes of property," does the sorting.

Separate property is what a spouse owned before the marriage or acquired after a dissolution decree, property a court designates separate, property acquired "by gift, bequest, devise or descent," and property the spouses designate separate "by a written agreement between the spouses, including a deed." The section defines property to include its rents, issues and profits, so income a separate asset produces stays separate. That puts New Mexico with the majority of community property states and apart from Texas, Idaho, Louisiana and Wisconsin, where income from separate property is community income.

Community property is defined by subtraction: "property acquired by either or both spouses during marriage which is not separate property." Wages earned during the marriage are community property, along with the house, vehicles and accounts those wages funded. Two presumptions back the definition. NMSA 40-3-12 presumes property acquired during marriage is community property, and 40-3-8 adds that property a couple acquires "by an instrument in writing whether as tenants in common or as joint tenants or otherwise" is presumed community property unless it qualifies as separate. Title does not settle character in New Mexico; how and when the asset was acquired does.

During life, NMSA 40-3-13 makes both signatures matter: the spouses "must join in all transfers, conveyances or mortgages" of community real property, and a transfer one spouse attempts alone "shall be void and of no effect."

What Each Half Does At Death

What it isWhere it goes when a spouse dies
Community propertyThe survivor keeps one-half under NMSA 45-2-807. The decedent's one-half passes by will or, with no will, to the surviving spouse under NMSA 45-2-102.
Community property titled in joint tenancyPasses to the survivor by the survivorship incident, outside the will and outside probate.
The decedent's separate propertyPasses by will or under the NMSA 45-2-102 intestate shares.
The survivor's separate propertyStays with the survivor. It was never part of the estate.

Debts follow their own order in 45-2-807(B): the entire community property answers for community debts, while the decedent's separate debts, funeral expenses and administration costs come first from separate property, reaching the decedent's half of the community only if the separate property runs short. What a New Mexico surviving spouse can claim covers the $30,000 family allowance and $15,000 personal property allowance that run ahead of general creditors.

One citation caution for anyone checking our work: the death rule was enacted in 1975 as Section 45-2-804, renumbered to 45-2-805 in 1993, and renumbered again to 45-2-807 effective 2012. Older articles, and even stray cross-references in the annotations, still point at the old numbers, whose current occupants govern divorce revocation and document reformation instead.

The intestate shares run spouse-heavy, with one lean fraction

NMSA 45-2-102 gives the surviving spouse the decedent's devisable half of the community property in every intestate case, so an intestate married decedent's community property ends up entirely with the spouse. Separate property is where children change the math: the spouse takes the whole intestate estate when no issue survive, and only one-fourth of the separate property when issue do. That quarter is leaner than most states give a spouse, and it makes the community-versus-separate sort the highest-stakes step of any married New Mexico intestacy. Who inherits in New Mexico without a will walks the full statute.

Joint Tenancy Is New Mexico's Survivorship Tool

Unlike Arizona, Nevada, Texas and Wisconsin, New Mexico has no "community property with right of survivorship" title form. NMSA 40-3-2 lists the ways spouses may hold property: "as joint tenants, tenants in common or as community property." The survivorship result comes from combining three rules:

  1. Property spouses take as joint tenants is presumed community property under 40-3-8(B).
  2. The Community Property Act preserves "the incident of the right of survivorship of joint tenancy" (40-3-8(F)).
  3. At death, 45-2-807(A) excludes "community property that is joint tenancy property" from the decedent's testamentary disposition.

So a home deeded to both spouses "as joint tenants" passes to the survivor automatically, outside probate, and a will that tries to leave the decedent's half elsewhere does not reach it. A couple who wants the decedent's half to be willable, to children of a first marriage, into a trust, should hold the asset as plain community property or tenants in common instead. Titling choices can also change the federal basis result covered below, so make them with both a lawyer and a CPA in the room. Ways to keep assets out of New Mexico probate compares joint tenancy with the transfer-on-death deed, beneficiary designations and trusts.

The Homestead Affidavit: A Probate-Free House For The Survivor

New Mexico gives a surviving spouse a recording shortcut most community property states lack. Under NMSA 45-3-1205, when a couple owned their homestead as community property and the decedent left it to the spouse by will or died intestate, "the homestead passes to the survivor and no probate or administration is necessary."

The mechanics are strict. Six months after the death, the spouse records an affidavit with the county clerk of the county where the home sits, swearing that the couple owned the homestead as community property, that apart from the homestead the estate needs no probate in any court, that no personal representative application is pending or granted anywhere, that funeral expenses, last-illness expenses and all unsecured debts are paid, that no federal or state tax is due, and that no one else has a right to the decedent's interest. The definition of homestead caps the home's value "as assessed for property taxation purposes" at $500,000, a measure that runs well below market value for most homes. For smaller personal-property estates, the separate collection-by-affidavit procedure under NMSA 45-3-1201 moves up to $50,000 thirty days after death, though it cannot transfer real estate.

Property You Brought From Another State

New Mexico defines quasi-community property and then uses it only once. 40-3-8(C) labels property a spouse acquired "while domiciled elsewhere which would have been community property" had the couple lived in New Mexico. Subsection (D) applies that label solely "[f]or purposes of division of property incident to a dissolution of marriage or a legal separation," and only when both parties are New Mexico domiciliaries.

No statute applies it at death. A couple who earned their savings in Oklahoma and retired to Santa Fe owns, at the first death, what Oklahoma law made of those earnings, and the half-and-half rule reaches only what became community property after the move. Couples who want the community result, and the tax treatment that follows it, can get there by written agreement: 40-3-8(A)(5) honors "a written agreement between the spouses, including a deed" as a way to designate character, and the same tool works in both directions. Have a New Mexico attorney draft it; the agreement moves creditor exposure and tax basis along with ownership.

What The Community Property Rules Do Not Do

  • They do not erase community debts. 45-2-807(B) subjects "the entire community property" to the payment of community debts at death. The survivor's half is not a creditor shelter while community obligations are unpaid.
  • They do not decide Medicaid recovery the way most states fear. New Mexico's Medicaid Estate Recovery Act defines the reachable "estate" as property "subject to probate or administration" (NMSA 27-2A-3), and NMSA 27-2A-7 permits recovery "only after the death of the decedent's surviving spouse" and never while a child under 21, or blind or disabled, survives. Property passing by joint-tenancy survivorship or the homestead affidavit sits outside the probate estate. Verify the current agency rules before relying on this; New Mexico Medicaid estate recovery covers the details.
  • They do not answer the second death. Everything the survivor ends up owning needs its own will, beneficiary designations or trust.

The Basis Answer That Rewards The Sort

Community property carries a federal income-tax advantage at the first death. 26 U.S.C. 1014(b)(6) treats the surviving spouse's one-half of community property as acquired from the decedent whenever at least half of the community interest was includible in the decedent's gross estate. Both halves of a community asset then take a date-of-death basis. An Albuquerque rental bought for $150,000 and worth $450,000 at the first death can give the survivor a $450,000 basis on the whole property, where a common-law-state couple would step up only the decedent's half. Property that stayed separate, and imported property never converted by agreement, steps up on the decedent's share only. Whether joint-tenancy titling of community property preserves the double step-up has its own federal tax history, so put that exact question to a CPA before selling. Your basis in inherited New Mexico property works the arithmetic.

Sorting Your Own Assets

Work asset by asset, in this order:

  1. When was it acquired? Before the marriage, it is separate under 40-3-8(A). During the marriage, 40-3-12 presumes it community.
  2. How was it acquired? Gift, bequest, devise and descent stay separate, along with their rents and profits. Earnings, and what earnings bought, are community.
  3. Where did the couple live at the time? Property acquired while domiciled in a common-law state keeps that character at death. Only a written agreement changes it.
  4. What does the deed say? "As joint tenants" adds survivorship and takes the asset out of both wills. Plain community title leaves the decedent's half willable.
  5. Did the couple sign anything? A 40-3-8(A)(5) written agreement or deed designation can reclassify in either direction.

Pull the deeds, account records and any agreements before deciding. Where the timeline crosses a move from another state, a remarriage, or a mixed-source account, hand the file to a New Mexico probate attorney.

Frequently Asked Questions

Is New Mexico a community property state?

Yes. IRS Publication 555 lists New Mexico among the nine community property states, alongside Arizona, California, Idaho, Louisiana, Nevada, Texas, Washington and Wisconsin. NMSA 40-3-8 defines community property as property acquired by either or both spouses during marriage which is not separate property, and NMSA 40-3-12 presumes property acquired during marriage is community property.

Who owns community property when a spouse dies in New Mexico?

NMSA 45-2-807 states the rule: upon the death of either spouse, one-half of the community property belongs to the surviving spouse, and the other half is subject to the testamentary disposition of the decedent. One exception rides along: community property the couple titled as joint tenants is not subject to the decedent's will, because the survivorship incident carries it to the surviving spouse directly.

Does the surviving spouse inherit everything without a will in New Mexico?

All of the community property, yes. NMSA 45-2-102 sends the one-half of the community property the decedent could have willed to the surviving spouse, on top of the half the survivor already owns. Separate property splits differently: the spouse takes the entire intestate estate when the decedent left no surviving issue, and only one-fourth of the separate property when the decedent left children or other issue.

Does New Mexico have community property with right of survivorship?

Not as a title form. NMSA 40-3-2 lets spouses hold property as joint tenants, tenants in common or as community property, and no statute creates a community property with right of survivorship label. New Mexico reaches the same result another way: property spouses title as joint tenants is presumed community property under NMSA 40-3-8, the survivorship incident is preserved, and NMSA 45-2-807 keeps that property out of the decedent's will.

What is the New Mexico homestead affidavit for a surviving spouse?

NMSA 45-3-1205 lets a surviving spouse take title to a community-property homestead without probate. Six months after the death, the spouse records an affidavit with the county clerk stating, among other things, that the couple owned the home as community property, the estate needs no other probate, unsecured debts and funeral expenses are paid, no tax is due, and the home's assessed value for property taxation does not exceed $500,000.

Does New Mexico have quasi-community property?

Only at divorce. NMSA 40-3-8 defines quasi-community property as property acquired while domiciled elsewhere that would have been community property in New Mexico, but the statute applies that label only to division in a dissolution or legal separation when both parties are New Mexico domiciliaries. No New Mexico statute recharacterizes imported property at death, so property brought from a common-law state keeps its character when a spouse dies.
